The invention relates to a latching connection for tubular parts, in particular for vacuum-cleaner accessory parts, such as suction tube, suction hoses, supplementary nozzles or the like, in the case of which connection two tube parts are pushed one into the other. Provided in the outer tube part are helical through-passages, over which there engage oppositely oriented protrusions on a spring-loaded adjusting ring which is arranged rotatably on the tube part. The inner tube part has cams which, when the tube parts are pushed one into the other, engage into the space between through-passages and protrusions and, at the end of this movement, are held by a type of hook. <IMAGE>
